POWER-TRANSMISSION APPARATUS.

Griginal application filed May 4, 1909,

To all whom it may concern:

Be it known that I, DAVID E. SnLDnRs, citizen of the United States,residing at Van Orin, in the county of Bureau and State of Illinois,have invented new and useful Improvements in Power-TransmissionApparatus, of which the following is a specification.

My invention relates to the transmission of motion to clothes washingmachines and clothes wringers, and consists in a oeculiar andadvantageous means, hereina er described and claimed, for controllingthe transmission of motion to a washing ma chine or other apparatus tobe driven.

The mentioned means for transmitting motion to clothes wringersconstitutes the claimed subject matter of my prior application filed May4, 1909, Serial No. 493,811, of which this application is a division,but for the sake of convenience I have illustrated and described hereinthe complete apparatus. a

In the drawings, accompanying and forming part of this specification:Figure 1 is a plan view of an apparatus constructed in accordance withmy invention. Fig. 2 is an enlarged detail perspective view takenfrom apoint at one end of the apparatus. Fig. 3 is a detail view takenapproximately at a right angle to Fig. 2, and showing the arrangement ofthe hand levers of the apparatus, relative to the uppermost portion ofthe main frame and the parts to which the said levers are connected.

Similar letters designate corresponding parts in all of the views of thedrawings, referring to which:

A is the main frame of the apparatus, and B is an auxiliary frame,preferably in the form of an upright, arranged at a suitable distancefrom the main frame. The. main frame A is provided with a dependingsleeve a which receives a post 6, fixed to a floor or other support (notshown), and is adjustably connected to said post by set screws 0 so thatthe main frame may be positioned at various heights to meet differentconditions. In addition to the depending sleeve a, the main framecomprises an upwardly extending portion 03 provided at an intermediatepoint in its height with a journal box 6 and also provided at its upperend with a head f, horizontally slotted at 9, Fig. 3, and forming partof a horizontally disposed platform 72.; an upwardly extending portion1: ar-

ranged opposite the portion (Z and separated therefrom by a space j; anda horizontally disposed journal box is arranged on said portion a andextending at a right angle from and in line with the transverse centerof the before mentioned journal box a.

J ournaled in the box 6 of main frame A and also in a bearing Z on theauxiliary frame B is a drive-shaft C, designed to be rotated by anysuitable motor through a band and the pulley m or through the medium ofany other expedient driving connection. The said shaft C is equippedwith clutch members D and E, fixed thereto by set screws or othersuitable means and arranged immediately adjaeent the ends of the box 6,miter gears F and G loosely mounted and movable endwise on the shaft Gand having circumferentially grooved portions 19, a clutch member Hsuitably fixed on the shaftand arranged, by preference, adjacent theauxiliary frame B, and a sprocket gear I loosely mounted and movableendwise on the shaft and having a guard r and a circumferentiallygrooved portion .9. It will also be noticed that the miter gears F andGr are provided with clutch members complementary to the clutch membersD and E, respectively, and that the sprocket gear I is provided with aclutch member complementary to the clutch member I-I. From this itfollows that when one of the miter gears F G is placed in engagementwith its clutch member D or E as the case may be, the said miter gearwill rotate with the shaft C but otherwise the gear will remain idle onthe rotating shaft; also, that when the sprocket gear I is placed inengagement with the clutch member I-I, said sprocket gear will be causedto rotate with the shaft but otherwise will remain at rest on therotating shaft.

Bearing in the journal box is of the main frame A, is a shaft J the saidshaft J being provided at its inner end with a large miter gear K, andat its outer end with a universal joint L, having in its outer member asocket such as illustrated to permit of its ready application to awringer such as at present in general use. The large miter gear K isarranged to cooperate with the miter gears F and G alternately, it beingobvious that when one of the said miter gears F or G is in en agementwith the gear K the wringer will be driven in one direction, while whenthe other miter gear F or G is in engagement with the gear K, thewringer will be driven in the opposite direction.

M is a yoke movable in the direction of the length of the shaft C andhavingloops t at its ends receiving the circumferentially groovedportions of the miter gears F and G.

N is a bar extending and movable through the yoke M and having a fork ustraddling the circumferentially grooved portion of the sprocket gear I.

P is a hand lever extending through and movable horizontally in the slot9 of the frame head f and connected at o with the yoke M.

R is a hand lever connected at w wit-h the bar N, and S is a boltextending through the platform h of the frame head f and pivotallyconnecting the levers P and R to said platform. At T the lever B isprovided with a friction-creating protuberance which is adapted bybearing on the upper side of the platform h under the pressure of I thelever possessed of more or less springiness, to hold the lever againstcasual movement without interfering with the manual operation of thelever.

By manipulation of the lever P, elther one of the gears F and G may bethrown into engagement with the gear K or the sald gears F and G may beboth positioned out of mesh with the gear K. From this it follows thatthe wringer actuated through the universal joint L may be readilystarted and stopped; also, that when the wringer is being driven in onedirection it may be eX- peditiously and easily reversed or driven in theopposite direction.

A single attendant is enabled to conveniently control both levers P andR, and by movement of the lever B said attendant may quickly and easilyestablish and interrupt connection between the sprocket gear I and theclutch member H and thereby start and stop the washing machine driventhrough the said sprocket gear. I would further invite attention to thefact that the levers P and R may be quickly and easily manipulated, andthat the apparatus as a whole is simple and compact, is susceptible ofquick and easy installation, and is well adapted to withstand the usageto which machinery of kindred nature is ordinarily subjected.

The construction herein illustrated and described constitutes the bestpractical embodiment of my invention that I have as yet devised, but itis obvious that in the future practice of the invention such changes ormodifications may be made as do not involve departure from the scope ofmy invention as claimed.

Having described my invention, what I claim and desire to secure byLetters-Patent, is:

In an apparatus for the purpose described, the combination of a framehaving at one end a platform disposed approximately at a right-anglethereto, a. shaft journaled in said frame, a gear on the shaft movableinto and out of driving connection. with the same, a resilient levermovable against the frame platform and pivoted at one end to the outerportion of the platform and having at its inner side and at anintermediate point of its length a friction-creating protuberance thatbears against and is slidable over the platform, and a bar connected atone end to the said gear and connected at its opposite end to the leverat the opposite side of the friction-creating protuberance, withvreference to the pivot point of the lever.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
